The purpose of this invention is to provide a fluorescent unit whichin itseltis completeand UNITED STATES PATENT OFFICE ends of the tube to which are attached plugs that Fi ate design may be pluggeddirectly into electrical socketsgd in 11 pl with the whereasltubes usingan electricalarc to actuate I e casing.

One of which changes use of a casingof any other shape another may be in the use'of still another may this design is indicated it, maybe formed as shown in 18 and IQ for 20 and 2| for tube 2. This plug is wired with one of the contacts l6 connected by a from the point l9 to with the length of the casing of the unit or the length of the casing may be made to correspond and the ected in the points of the end mat stop at the base plug, the function of which provide between the control unit opposite and the terminals of with the other terminal wire 25 26 and from the point 26 back to the wire l3.

1. A lighting unit for fluorescent tubes comprising an elongated base compartment, a conterminal of the control unit is connected by the trol unit in said compartment, an outer compartment with a reflecting inner surface, a fluorescent tube positioned in the outer compartment, and circuit carrying plugs at the ends of said unit providing connecting means between the control which the plugs are .unit and tube, and with one of said plugs adapted to provide contacting means for supplying current to the unit.

2. A lighting unit as described in claim 1, in provided with prongs adapted to be inserted in wall sockets.

3. A unit as described in claim 1, in which the connection to the circuit is made through one plug only.

4. A lighting unit for fluorescent tubes, comprising an elongatedbase compartment, 9. control unit in said base compartment, an outer compartment, a fluorescent tube insaid outer compartment, and removable plugs at the ends of the unit having sockets and connectors providing connecting means between the control units and light tube and between the control unit and a source of current supply.

5. A lighting unit for fluorescent tubes, comprising a base compartment, a control unit in those of said base compartment, an outer compartment, a fluorescent tube in saidouter compartment, and plugs at the ends of the unit having sockets and connectors providing 'connecting means between the control unit and lighttube and asource of current supply.

6. A lighting unit for fluorescent light tubes comprising a relatively long narrow casingwith contact prongs extending at the ends with the prongs at onei end spaced further apart than the other, said casing adapted to house a control unit with the terminals of the unit connected with the prongs, plugs having receiving sockets adapted to be placed on the said prongs,

the ends said plugs, said plugs having additional sockets for the terminals of a light positioned upon the casing, said unit characterized in that the 'plug at one provides connections from the control unit to the light tube and one of the prongs or the plug at the other end connects with one of the receiving sockets with the other receiving socket connecting with one of the tube sockets and the other tube socket connecting with the other prong extending from the end of the plug.
